Stored factory profiles: These are profiles 2 to 40 as selected with DS1. They are stored in the factory and can be used as they are or changed and stored on profile 0 or 1. Factory profiles can be custom made on request. Contact MuLogic support for further information. AT command conventions Unless specified otherwise, all command lines must begin with the AT attention code. - Page 18 User Guide – Configuration Leased Line Data Modem LLM-336 Using settings of factory profiles for 11bit async. mode For example, factory profile 13 (9600 bit/s V.34 asynchronous) is configured for 10 bit data format operation. This can be used for asynchronous data formats like 9600-8-N-1, 9600-7-E-1 and 9600-7-O-1.

Page 21: Asynchronous Operation
Leased Line Data Modem LLM-336 User Guide – Configuration Asynchronous For asynchronous operation, it is important that the configuration commands are entered in the speed and data format at which the modem operation must operate. So, if the modem must work at an asynchronous data format of 8 data bits and Even parity, the configuration commands must be given in this format. - Page 22 2400 bit/s. Asynchronous buffered mode The LLM-336 supports a buffered interface for asynchronous data in all modem modulation modes. This allows for the attached device to run at a serial port rate other than the line speed of the modem.

Page 24: Half Duplex Operation
V.27bis and V.33 are less effective for half-duplex use with short messages as in these modes the RTS-CTS times are quite long. Note: the V.23, V.27, V.29 and V.33 modes in the LLM-336 modem can only operate in half-duplex, regardless if 2-wire or 4-wire operation is selected. - Page 25 TxD data input. As soon as the block of data has left the transmit data buffer, the transmitter will stop sending and the receiver will be enabled. In ACC mode, the LLM-336 has a feature to suppress the spurious or garbage characters that occur at the RxD output when the remote modem’s carrier is dropped.
- Page 26 User Guide – Configuration Leased Line Data Modem LLM-336 For half-duplex operation the following commands apply: Half duplex modulation modes See page 3-4 AT%H Half duplex carrier control modes AT%H0 Half duplex operation disabled (Set in +MS full-duplex modes) AT%H1 Half duplex operation with RTS carrier control AT%H2 Half duplex operation with RTS control.

“slave” modem the receive the poll requests and return the poll responses. Note: The LLM-336 can be used on 2-wire and 4-wire lines. However, on both 2-wire and 4-wire lines, the communication is half duplex, which means that the modem is either transmitting or receiving. -
Page 28: Transmit Level
User Guide – Configuration Leased Line Data Modem LLM-336 The default value of the transmit level is –11dBm (at 600Ω). This value is Transmit level suitable for nearly all applications. The transmit level can be changed by means of registers S91 and S92. Note that transmit levels higher than –11dBm may be in violation with the rules for operation on public leased lines. -
